Iran's kaleidoscopic ceilings, in pictures

Meanwhile, another stunning image shows the ceiling of Sheikh Lotfollah Mosque. Mohammad described: "Upon entering I was met with turquoise mosaics, streams of light from the windows in an otherwise dimly lit space shone onto the tiles, walls and scriptures of Quran, giving the place and ethereal feeling. Before taking this photo I entered the Mosque many times, taking in and relishing its beauty for many hours."
